|Title||Do Ultraluminous Infrared galaxies harbor narrow-line Seyfert nucleous|
|Author||Mr Naohisa Anabuki|
|Description||Ultraluminous infrared Galaxies (ULIRGs) are interacting galaxies with infrared luminosity comparable to quasars.An evolutionary relation with quasars are strongly suggested, but the origin of their infrared emission (SB or AGN) is still a major issue under debate. Our recent study of ULIRGs observed with ASCA suggests that the AGN in ULIRGs generally indicates the features of narrow-line Seyfert 1 galaxies(NLSy1s). This might be the evidence that the AGN in ULIRGs has a light blackhole and high mass accretion rate, and hence is now under evolution to a quasar.To examine the properties of the AGN in ULIRGs directly and reveal the connection with quasars, we propose systematic observations of type 1 ULIRGSs with XMM-Newton.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
